COMBINED WOOD SAWING AND SPLITTING IVIACIIINIEI.l

Application filed June 15, 1923. Serial No. 645,611.

The invention relates to improvements in combinedwood sawing andsplitting machines and an object of the invention is to provide a powerdriven machine for sawing wood poles into blocks and subsequentlychopping or splitting the blocks, there being suiiicient choppingcapacity to conveniently handle al] the blocks 'cut by the saw.

A further object is to provide a machine wherein the handling of thewood is reduced to a minimum, the eut sticks or blocks being passed fromthe saw to a position adjoining the chopping blocks by a conveyor.

A further object is to arrange the driving mechanism such that both thesaw and the axes can be driven by aV single source of power, such as aninternal combustion engine mounted on the machine or by a portableengine adjacent the machine.

A still further object of the invention is to provide a feed table orcarriage for supporting one end of the pole to be sawn and which is`arranged such that it will automatically'feed the pole to the saw andsuch that no pinching of the saw in the cut can occur.

A further object of the invention is to provide a combined sawing andchopping machine, the frame of which is arranged such that it can bemounted on trucks, sleighs, skids, or other desired mounting.

Vith the above more important objects in view the invention consistsessentially in the arrangement and construct-ion of parts hereinaftermore particularly described and later pointed out in the appendedclaims, reference being had to the accompanying drawings in which:

Fig. 1 is a side view of the complete machine as it appears mounted on atruck body.

Fig. 2 is a plan view of the same.

Fig. 3 is a vertical sectional view longitudinally through the machine,the section being taken at 3 3 Fig. 2.

Fig. 4 is a vertical cross sectional View at 4-4 Fig. 3.

Fig. 6 is a side view of the feed table or carriage and parts associatedtherewith.

Fig. 7 is a vertical cross sectional view at 7 7 Fig. 6.

Fig. 8 is a perspective view of one of the p splitting axes.

In the drawing like characters of reference indicate corresponding partsin the several figures.

The machine can be mounted in any suitable manner for transportingpurposes and in the present instance is shown as mounted on a truckframe embodying the front and rear axles 1 and 2, wheels 3, front andrear bolsters 4 and 5 and thereach G connecting the axles. This truckframe is 0f the ordinary wagon type and further details thereof are notconsidered necessary.

The sawing machine frame 7, which is substantially rectangular,comprises a pair of similar side beams 3 and 9 connected rearwardly by apair of spaced cross beams 10 and 11 and forwardly by a platform 12, theplatform supporting a source of power, such as an interna-l combustion13. The frame 7 is designed such that it can be seated on the bolstersof the truck frame, the beams 1() and 11 receiving the rear bolstertherebetween, whilst the forward ends of the beams 3 and 9 are receivedbetween pins 14 and 15 carried by the front bolster. These pins preventlateral shifting of the forward end of the frame 7 and the beams 10 and11 prevent end shifting. The frame 7 is fastened to the rear bolster bypins 16 extending upwardly from the bolster into the beams S and 9.

By the above arrangen'ient it is a very easy matter for one to dis'mountthe machine from the truck frame and put it on any other type of frame,such as sleighs, skids, or such like.

The engine drive shaft 17 is provided with a pulley 18 which carries abelt 19 operative over a further pulley 2O located on a counter shaft 21carried in suitable bearings 22 mounted on the beams 8 and 9.Iil'imediately to the inner side of the beam S and on the counter shaftI mount a wood cutting saw 23 which is of the ordinary type', and to theopposite end of the counter shaft I secure a combined balance and flywheel 24 with which I associate a comparatively small pulley 25, Thesawis in` this way driven directly from the engine and rota-tes in thedirection indicated by the applied arrow, Figure 3.

Adjoining the outer face' of the beam 8 I locate a short beam 26 whichis spaced from Lthe main beam to provide a vertical slot 27.

A carriage or feed table 28 is supplied for supporting the end of the.stick or pole to be sawn. This carriage'in the' present instance is inthe form of a substantially reetangular metallic plate fitted withupstanding end flanges 29 and 30,A each-'flange being cut t provide a.V-shaped recess 3l.

The plate is also'supplied on the underside' with a centrally positionedtin like extension 82 which is slidably receivedwithin the slot 27. Thep carriage is 'supported for swinging movement towards and away from thesaw by a pair of hangers 33 andY 34 which have theirlower ends pivotallysecured at 35 to the front land rear ends Aof thevcarriage andtheirupper ends pivotally secured by bo-lts 36 to bearings 37Hperma nentlymounted. on the outer of a vpair' of elevated beamsSS and 39. A coiledspring connects one of the hangers to the beam 38 and 'acts to hold thecarriage .normally in its back position or withdrawny from the saw.Theends'of the slot limit the forwardland backmovement of the carriageand the spring is gauged such that it will draw the unloaded carriagebackrkbut is not strong' enough' to prevent the carriage movingaheadunder the added weight ofthe vpole or stick of wood, the endof whichisrested on the carriage andl in the notches 31 when the same is to bec-ut.

By observing the position of the carriage sbownjin the drawings it willbe seen that upon one end of the wooden pole being placed on thecarriage the added weight willcause .the carriage to swing ahead towardsthe saw and against the action of the spring and in so doingautomatically feed the pole to the saw by which itis cut. In

this lconnection it is to bev understood that one end of the pole to besawn is rested on the-carriage and the other end is held up by theattendant. fis soon as the cut is made by thel saw the attendantrelievesv the carriage ofa goodly portion of the weight of the unsawnpart of the pole and the carriage automatically returns to its originalvposition under the influence of the spring. 'lfheattendantalso-,advances thevpole the proper distance Vfor the nextcut and uponlettirge; the weight of the pole come again onto the carriage thefollowing cut is made in the same manner as the. first out, the carriageadvancing to the'saw.

`vletween the side beams of the frame 7 I locate an endless conveyor 4lwhich is formed from similar endless chains 42 operating over Vsimilarchain wheels 43 mounted on conveyor shafts 44 and 45 suit-.ablyjcarriedrin bearings provided on the beams 8 and 9. Thechains'areconnected Aby suitably spaced cross slats 46 Yand the upperlsides of the chains operate over a cross plate47 interposed between thebeams and supported thereby. The plate is out iirecting rods 75l and76;l

standing' flange 48. This conveyor, which is driven ,as later described,is adapted to catch the shortsticks'cut bythe saw and carry .themrearwardlyto the end of the machine where they are 'thrown ofi' onto apan 49 suitably` supportedl from the rear end of the fran1e7;f3A i n Atransmission shaft 50 is located'rearwardly of the machine, beingcarried by suitablebearings 5l secured to the under sides ofthe beamsSand -9 This shaft is driven from they saw shaft 21v by ya belt 52connecting the pulley 25 ywith, a pulley 53 on the transmissionl shaft.1f w. f

VfIhe transmission shaft drives the conivieyor, such beingAaccompljish'ed by an endless chain 54 imn'iediately'at'the inner sideof the :beam 9 and operating onchain wheels 55 andA 56 secured to thetransmission shaft andthe forward conveyor shaft respectively. Atthe.rear end of the platform I locate a crank vshaft 57 whichfisiitted withtwo oppositelydisposed cranks 58and 59 and is carriedbyj pairs of endbearings (i0 andl suitably mounted onplates 6,2' carriedby'the beams 8and 9. The crank shaftqisfitted at the, end with comparatively large flywheelsGS andy 34 and thefly wheel v 63 is connected to the adjacent@endpftl'ie transirrission shaft byr a belt which operatesfon a flangedpulley 66 seeured'to the transmis sionL shaft. l s ,i

Therbeams 38 and 39 .arespaced apart and". are duplicated at theopposite sider 0f the vmachine. and they are supported at thenends byyupright rposts A67' yand A168. Brace beams 69 yand 70 extend ybetweenthe opposing posts at oppositesides oftheframe. Between thepairs ofbeams SSUandv 39 I mountv similar rocker'beams 71 and 727 these beingpivotally :carried by, pivot pins 73 mounted on the'` top sides of thebeams 38 and 39 and fastened tothe rocker beams by suitable ,straps 74.The forward ends of the rocker beams which it Awill be observedloverhang the cranks of the crank shaft are respectively connected tothecranks by .-.con-

The'rear ends of the rocke'beams carry Asimilar splittinga'xes :77;and78 whiclrhave their cutting edges down and the arrangement is such thatin the rotation of the crank shaft the axes alternately raise and lowerto chop andwithdraw from ,the cut.' TheQaXes are f guided betweenextending pairs of Lbrackets `79 andSO permanentlyfsecured to thereariposts and the beams 38 and 39. In

.this connection I ,might mention that the upper ends of the postsarearranged to guide the rocker beams so that no lateral spo ' play ofthe axes is permitted. The axes operate directly Vabove similar choppingblocks 81 and 82, these blocks being comparatively heavy metallic platescarried by the rear ends of the beams 8 and 9 and amply reinforcedunderneath. It will be observed that the upper faces of the blocks arecheckered or otherwise roughened, such preventing the base of the blockfrom side slipping, as might occur if the end of the block were cut atan incline. It will also be noticed that the chopping blocks are locatedimmediately to the side of the rear end of the conveyor and also withinconvenient range of the pan 19.

Various parts of the machine can be reinforced by metallic straps orbraces as occasion demands.

The platform 12 is preferably demountably connected to the beams so thatit can be removed if desired. Obviously one might have a small t-ractoror portable engine which he wished to use instead of the engine 13.Accordingly, by dismounting the engine 13 and platform 12 one would beenabled to connect the portable engine to the driving pulley 20.

IVhen sticks or poles of wood are to be sawn, one person wouldmanipulate the poles to feed them to the saw and two other persons wouldstand to the rear of the chopping block and take the cut sticks andpresent them to the axes. As before explained, the carriage wouldadvance the pole to the saw without any effort on the part of theattendant other than the holding up of the free end of the pole and theraising and end shifting' of it to make the further cut. The shortsticks cut by the saw falling onto the conveyor are carried back andthrown onto the pan where they are picked off by the other twoattendants, placed on end on the blocks 81 and 82 and subsequently splitby the down coming axes. The split sticks can then be thrown into pilesby the attendant.

Obviously, the machine has a considerable cutting and chopping capacityand all unnecessary handling of the wood is dispensed with. The two axeswill readily handle everything cut by the saw so that no time is lost.

What I claim as my invention is:

l. In a combined wood sawing and splitting machine, a frame, a drivenrotatably mounted saw positioned centrally of the frame and locatedtowards one side thereof, a pair of pivotally mounted elevated opposedrocker beams located at opposite sides of the frame and extendinglengthwise thereof, said beams having their rear ends overhanging therear ends of the frame, a wood splitting axe secured to the rear end ofeach rocker beam, said axes being reciprocated in the vertical plane inthe rocking of the beam, means for alternately reciprocating the forwardends of the beams to give a chopping and return stroke to each axe,chopping blocks located at the rear corners of the frame beneath theaxes and a driven endless conveyor mounted within the frame and adaptedto receive the wood blocks cut by the saw and deliver the samerearwardly to the chopping blocks.

2. In a wood sawing and splitting machine, a substantially rectangularframe having therear part thereof open, a rotatably mounted saw shaftcarried by the frame and passing across the same, a wood cutting sawsecured to the shaft and located at one side of the frame, a pair ofopposed lengthwise extending elevated and pivotally mounted rocker beamscarried by the sides of the frameand having their rear ends overhangingthe rear part of the frame, chopping axes secured to the rear ends ofthe rocker beams, chopping blocks mounted on the frame beneath the axes,a forwardly positioned transversely extending driven crank shaft havingthe cranks thereof oppositely disposed, connecting rods connecting thecranks with the forward ends of the rocker beams and a driven endlessconveyor mounted within the rear part of the frame and adapted toreceive the blocks cut by the saw and deliver the same rearwardly to alocation adjoining the cutting blocks.

3. In a combined wood sawing and splitting machine, a substantiallyrectangular frame having the rear part open a transversely extendingrotatably mounted saw shaft mounted centrally on the frame, a woodcutting saw secured to the shaft and positioned within but towards oneside of the frame, a pair of opposed elevated lengthwise extendingpivotally mounted rocker beams carried by the sides of the frame andsuitably guided for vertical swinging movement, said beams having theirrear ends located above the rear ycorners of the frame,

similar chopping axes secured to the rear ends of the rocker beams,chopping blocks mounted on the rear corners of the beams beneath theaxes, a forwardly positioned transversely extending crank shaft carriedby the frame and having the cranks thereof oppositely disposed,connecting rods connecting the cranks with the forward ends of therocker beams, an endless conveyor mounted within and carried by the rearpart of the frame and adapted to receive the wood block cut by the sawand deliver the same towards the chopping blocks, and means for drivingthe conveyor, saw shaft and crank shaft.
